The amount of rainfall can be used to estimate the runoff that enters a reservoir. Runoff is influenced by land use, and soil type greatly affects will occur. This study discusses development hydrological model with application Hydrologic Engineering Center (HEC-HMS) in Karangmumus watershed using data has been verified field divided into zones based on permeability testing laboratory. With hel...

This paper shows the combined use of remotely sensed data and hydraulic geometry methods as an alternative to rainfall-runoff models. Hydraulic geometric data and boolean images of water sheets obtained from satellite images after storm events were integrated in a Geographical Information System. Channel cross-sections were extracted from a high resolution Digital Terrain Model (DTM) and superi...

[1] The Soil Conservation Service curve number (SCS-CN) method is widely used to predict storm runoff for hydraulic design purposes, such as sizing culverts and detention basins. As traditionally used, the probability of calculated runoff is equated to the probability of the causative rainfall event, an assumption that fails to account for the influence of variations in soil moisture on runoff ...

Soil Conservation Service (SCS) and overland flow models have been used for runoff modeling over major land mass of India. Remote sensing derived daily rainfall data (Climate Prediction Centre), high temporal NDVI data (SPOT VGT), DEM (GTOPO30) and soil texture maps were used as input for the runoff modeling. SCS model setup was done in GIS (Arc GIS) environment. In general the reported and mod...

This paper presents the implementation of a new data model for simulating watershed runoff. This data model, called nen, allows users to visualize and analyse the processes that are simulated in the watershed runoff model. It extends data models typically used in modelling watershed runoff, such as raster, that do not give direct insight into the spatial dynamics and distribution of the process...

River flow assessments and ecologically sustainable water management plans are now possible due to the advancement of sophisticated computer models. The US Army Corps Engineers developed HEC-HMS model, which can be used for various hydrological simulations. Rainfall-runoff modeling aids in estimating peak flows, is critical resource planning. On December 18, 2017, a heavy rainfall event ungauge...
